Working Principle of ASTMHTA-120.000MHZ-XJ-E-T

The ASTMHTA-120.000MHZ-XJ-E-T utilizes a quartz crystal as its timing source. The oscillator is temperature compensated, meaning that temperature changes do not affect the device’s frequency output. This is achieved by a temperature stabilization circuit that constantly monitors the device’s ambient temperature.The oscillator utilizes a phase-locked loop (PLL) circuit to stabilize and control the frequency. The PLL uses a feedback circuit to compare the output frequency with an accurate reference frequency drawn from the quartz crystal. If the output frequency deviates from the reference, the PLL circuit will automatically adjust the output frequency until it matches the reference frequency. This ensures the highest accuracy and stability of the oscillator.

Conclusion:

In conclusion, the ASTMHTA-120.000MHZ-XJ-E-T is an oscillator developed by the Chinese manufacturer Astmhta Electronics which has a fixed output frequency of 120.000MHz. It is suitable for applications in radio networks, communication systems, automotive electronics, industrial control, and other commercial and consumer electronics, due to its high accuracy, stability, and reliability. The device utilizes a quartz crystal as its timing source and a phase-locked loop (PLL) circuit to stabilize and control the frequency, ensuring the highest accuracy and stability of the oscillator.
